The another side of plate 4 is divided into four regions, and one is both provided with each region and divides speculum 6 in 45° angle with substrate 4, and
And the reflection direction of this four points of speculum 6 differs,
Described drive mechanism 3 includes a flat turn motor 7 being fixedly installed at the top of projector space, the work of flat turn motor 7
The driving tooth 8 made on end engages with passive tooth 9, and passive tooth 9 is arranged on the top of swivel mount 10, is set in the bottom of swivel mount 10
Have upset motor 11, the working end of upset motor 11 is connected with trip shaft 12, and trip shaft 12 then key connection in described substrate 4
It is interior, and a symmetrical overlapping of axles of the axis of trip shaft 12 and substrate 4,
Described projector 1, flat turn motor 7 and upset motor 11 is controlled by control system.
The utility model compared with the existing technology, has the following advantages that：
The optical projection system of more projecting directions of this kind of structure type, its is simple in construction, ingenious in design, rationally distributed, and it is created
Two kinds of reflection units are provided with to the property made, a kind of reflection unit is a speculum horizontal by 45 ° of angles, and it can be incited somebody to action
Projection ray is reflexed on metope, and the speculum can allow projected picture in 360 ° of scope internal rotations（Successively）It is incident upon
On all metopes of projector space；And another reflection unit then can be simultaneously to the reflection projected on four direction for one
Mirror, this speculum can respectively launch the four independent projected pictures played in projector on different metopes, and one
Secondary property shows multiple different image frames, it is cost-effective simultaneously, additionally it is possible to increase the interest of viewing.It is and this
The manufacture craft of optical projection system is simple, and manufacturing cost is cheap, it can be said that it possesses a variety of advantages, particularly suitable at this
Popularization and application in field, its market prospects are very wide.

Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figures 1 to 4：A kind of more projections
The optical projection system in direction, the system are located at projector space including one（Such as room）Projector 1 at center, and this is thrown
The projecting direction of shadow machine 1 is upward, speculum 2 is provided with the top of projector 1, and this speculum 2 is connected to driving machine
On structure 3, and perspective plane is provided with four walls of projector space；
Above-mentioned speculum 2 includes a substrate 4, and the one side of this substrate 4 is provided with principal reflection mirror 5, and principal reflection mirror 5
It is in 45 ° of angle between substrate 4；And the another side of substrate 4 is then divided into four regions, one is both provided with each region
It is individual to divide speculum 6, and these divide the reflection direction of speculum 6 different, i.e., and this four points of speculum 6 can be by light point
Do not reflex on the four direction of the four corners of the world；
Above-mentioned drive mechanism 3 includes a flat turn motor 7 being fixedly installed at the top of projector space, in flat turn motor 7
Working end on be provided with driving tooth 8, the driving tooth 8 is meshed with passive tooth 9, and passive tooth 9 is then arranged on swivel mount 10
Top, this rotating support of swivel mount 10 are provided with upset motor 11, institute in the bottom of swivel mount 10 at the top of projector space
Trip shaft 12 of the working end of upset motor 11 with rotating support on swivel mount 10 is stated to be connected, and described trip shaft 12 then key
It is connected in above-mentioned substrate 4, and a symmetry axis of the axis of trip shaft 12 and substrate 4 overlaps；
Above-mentioned projector 1, flat turn motor 7 and upset motor 11 is uniformly controlled by control system.
The course of work of the optical projection system of more projecting directions of the utility model embodiment is as follows：Need to watch projected picture
When, control system control projector 1 works, and projects light upwards, light produces reflection in the presence of speculum 2, and throws
It is mapped on the perspective plane in projector space, is watched for the personnel in projector space；
When the light of projector 1 is shone directly on principal reflection mirror 5, because principal reflection mirror 5 and horizontal direction are in 45 °
Angle, therefore it can reflex to picture on perspective plane, be watched for people；Control system can also control flat turn motor 7 simultaneously
Work, passive tooth 9 and the unitary rotation of swivel mount 10 are driven by driving tooth 8, it is final to drive principal reflection mirror 5 to rotate, allow shadowgraph
Face is also moved successively on different perspective planes therewith, obtains interesting higher viewing experience；
When the light of projector 1 is shone directly on four points of speculums 6, projector 1 is disposable to project four simultaneously
Individual independent picture（The common projector of this function is fully able to realize）, this four pictures pass through different speculums respectively
6 reflex on different perspective planes, that is to say, that on the different directions of a projector space, only with a projector 1
Obtain four different image frames；
When needing to switch in two kinds of speculums, it is only necessary to which control system sends signal to upset motor 11, upset
Motor 11 drives trip shaft 12 to rotate, and due to key connection between trip shaft 12 and substrate 4, and trip shaft 12 passes through substrate 4
One symmetry axis, therefore it can drive substrate 4 to invert completely, allow the upper and lower surface of substrate 4 to overturn, and realize the institute of principal reflection mirror 5
And divide where speculum 6 while switching.
